我正在尝试使用Microsoft Identity Web-NuGet添加可选声明,以在NET Core 3.1 WebApp中进行用户身份验证。阅读MS Docs,似乎所需的唯一步骤是在Azure的App Registration Manifest文件中声明可选声明。但是,当使用两个不同的应用程序(我自己的代码和一个MS项目示例)测试登录过程时,成功登录后从Azure返回时似乎没有将可选声明添加到ID令牌中,即它们根本不存在在调试中查看令牌详细信息时。
我不确定如何诊断该问题以及在何处跟踪该问题,即我是否缺少Azure安装程序中的所有必需步骤?
侧面注意:只是要确认这是我要接收其他声明的jwt ID令牌,而不是用于调用图形或另一个Web API端点的jwt访问令牌。
MS Docs参考:v2.0-specific optional claims set
以下是清单文件的摘录:(请注意,我什至已经声明了“ accessTokenAcceptedVersion”:2,因为我正在使用的可选声明在版本1中不可用,如果上述内容保留为默认设置, 'null'值,然后Azure将假定我们正在使用旧版Ver.1-可能的陷阱
"accessTokenAcceptedVersion": 2,
"optionalClaims": {
"idToken": [
{
"name": "given_name",
"source": "user",
"essential": false,
"additionalProperties": []
},
{
"name": "family_name",
"source": "user",
"essential": false,
"additionalProperties": []
}
],
"accessToken": [],
"saml2Token": []
},
从启动类中提取:

// Added to original .net core template.
// ASP.NET Core apps access the HttpContext through the IHttpContextAccessor interface and

services.AddHttpContextAccessor();
// DO NOT DELETE (for now...)

Razor PageModel样本方法:
public void OnGet()
{
var username = HttpContext.User.Identity.Name;
var forename = HttpContext.User.Claims.FirstOrDefault(c => c.Type == "given_name")?.Value;
var surname = HttpContext.User.Claims.FirstOrDefault(c => c.Type == "family_name")?.Value;
_logger.LogInformation("" + username + " requested the Index page");
}
更新
更接近解决方案,但还不完全解决。解决了几个问题:
最后一个尚未解决的问题是,尽管我可以看到Debug期间存在的声明,但是我无法弄清楚如何检索声明值。
在下面的方法中,使用Debug时可以看到所需的声明,但无法弄清楚如何检索值:
public void OnGet()
{
var username = HttpContext.User.Identity.Name;
var forename = HttpContext.User.Claims.FirstOrDefault(c => c.Type == "given_name")?.Value;
var surname = HttpContext.User.Claims.FirstOrDefault(c => c.Type == "family_name")?.Value;
_logger.LogInformation("" + username + " requested the Index page");
}
Debug屏幕截图显示了给定名称和家庭名称存在:
我尝试使用Claims主体尝试不同的代码示例,以尝试获取值,但对我来说没有任何用。对于知道所需语法的人来说,希望这个最后的谜语是相当简单的,正如我们现在所说的,现在存在所需的可选声明,只是不知道如何实际获取值。
答案 0 :(得分:0)
非常感谢“ Dhivya G-MSFT身份”的帮助(请参见我的原始问题下方的注释),下面的方法现在使我能够从成功登录后从Azure返回的令牌ID中访问所需的索赔值。
public void OnGet()
{
var username = HttpContext.User.Identity.Name;
var forename = HttpContext.User.Claims.FirstOrDefault(c => c.Type == ClaimTypes.GivenName)?.Value;
var surname = HttpContext.User.Claims.FirstOrDefault(c => c.Type == ClaimTypes.Surname)?.Value;
_logger.LogInformation("" + username + " requested the Index page");
}
